Finally, a compact AR pistol with the energy of an M4 carbine, and without the abusive concussion of 5.56mm.
There are two separate paths to Short Barrel Rifle ownership. The first, traditional method, is to visit your local dealer that sells National Firearms Act firearms and purchase a factory "SBR", ready made. Your dealer with transfer it to you on a Form4, with a $200 tax paid to BATFE. While your paperwork is being approved, your new SBR has to remain in the custody of the dealer until approved by BATFE. This approval can take over six months.
The second path to ownership is to "Make your own". This involves taking an existing firearm, like an AR pistol and fill out a Form1, which is an application to "make a firearm". Simply fill in the information about the Short Barrel Rifle you wish to make, send it off with your $200 check and wait for the approved form before replacing the stock to create the Rifle. The advantage here is that while you are waiting on your paperwork approval, the pistol is in your possession, not locked in your dealers safe for months.
300 AAC Blackout, created by Advanced Armament Corp. and Remington Arms® , is a reliable 30-caliber solution for the AR-15 platform that uses existing 5.56mm magazines for a full 30 round capacity. The highly-efficient cartridge can change between standard full power ammunition and quiet-when-suppressed subsonic loads without any adjustments needed to the firearm. 300 BLK has as much energy from a 9 inch barrel as 5.56mm does from a 14.5 inch barrel, all while having less flash, blast, and noise.
Even from a 9 inch barrel, 300 BLK with Barnes® ammunition expands to more than 50 caliber and penetrates 20 inches of 10% ballistic gelatin at 300 yards. Being 30 caliber, 300 BLK is less effected by obstacles, such as automobile glass, than 5.56mm. The gain in frontal area from 5.56mm to 30 cal is 89.1% - even more of a boost than the 60.7% size advantage that 45 Auto has over 9mm. 300 BLK is a SAAMI standard cartridge that is supported by over 150 companies.

The information below comes from our Gun Caliber Dictionary and is for
general reference only. It does not describe the specifications of this
particular item.
The 300 AAC Blackout (300 BLK) was developed in 2009/2010 by Advanced Armament Corporation and approved by Sporting Arms and Ammunition Institute (SAAMI) in 2011. Based on the 223 Remington case necked up to 30-caliber, it was intended for the M4 Carbine and designed to function in standard AR15/M16 magazines. Thus converting an AR to 300 AAC Blackout requires nothing more than an upper receiver group. Dimensionally it is identical to the 300 Whisper, but the 300 Blackout is fully standardized. Supersonic and subsonic ammunition is manufactured, with a 125-grain bullet producing 2215 feet per second, while the subsonic load uses a heavier bullet at much lower velocity: 220-grain bullet at 1080 fps. Military applications are obvious; as a sporting cartridge performance is similar to the 7.62x39.
